Problem getting JavaBean value
I'm using jakarta-taglibs-standard-1.1.0-B1 with JSP 2.0 and Tomcat 5.0.16.
I have a bean that has the following accessor method.
public String getCNetId() {
return cNetId;
}
I'm attempting to get the value in a JSP using the following,
<c:out value="${courseSiteRequest.cNetId}"/>
but, I'm getting the following error,
javax.servlet.ServletException: Unable to find a value for "cNetId" in
object of class "edu.uchicago.at.coursesiterequest.CourseSiteRequest" using
operator "."
If I change the case to the following, it works.
public String getCnetId() {
return cNetId;
}
<c:out value="${courseSiteRequest.cnetId}"/>
Is this a bug?

OK, thanks. I was trying to locate that spec yesterday on Sun's Web site,
but, couldn't seem to find it.

Nope, the Introspector does not lie ;-). Quote from the Javadoc:
This normally means converting the first character from upper case to
lower case, but in the (unusual) special case when there is more than
one character and both the first and second characters are upper case,
we leave it alone.
This is also covered in section 8.8 "Capitalization of inferred names"
of the JavaBeans Spec.

That worked, but, shouldn't it have made the first character lowercase?

Try:
"${courseSiteRequest.CNetId}"
You can use java.beans.Introspector.decapitalize as a sanity check for
your property names.
